title: A comparison of spring and CO2- powered needleless injectors in the treatment of keloids with triamcinolone.
abstract: A comparison has been made between the traditional needle and syringe technique of injection and two differing types of needleless injector in the intralesional treatment of keloids with triamcinolone. This most reliable method of delivering a known quantity of drug into a keloid is by syringe and needle. However, the CO2-powered injector is far more reliable than the spring-powered injector in the reliability of the dose administered and its intralesional penetration and distribution.
